Which is better, Polkadot or Chainlink?

I'm curious to know, could you please elaborate on the relative merits of Polkadot and Chainlink? As I understand, both platforms offer unique functionalities in the blockchain ecosystem, but which one do you consider to be superior? Could you compare their scalability, interoperability, and the potential for future growth? Additionally, how do their respective tokenomics and governance structures compare? I'm particularly interested in your expert opinion on which platform might offer better opportunities for investors and developers alike. Thank you for your insights.
